Is writing learning

I would like for writing to be learning. It would be easier for me as a teacher for my grandson. I could teach the lesson and give him the book and he could go away, write the lesson and leave me alone. He wants to go back to the public school system; as this to him is normal.For him to go to the public school system, he needs to be able to do his work independantly, and write his work. I have been trying to use this and it is not working for him. Today I did his English Grammar orally with him and had a very pleasant class and he seemed to learn better. He did his fractions work well and seemed to understand it also. We used the Math U See fraction pieces. He liked them and seemed to understand how adding fractions needed to use a common demoniator.
